NERVINE SECRETION 395 



and has provided for its removal, or elimination, an 

 excretory duct or ducts ; therefore, in instituting this 

 comparison we have not been unmindful of the require- 

 ments of the situation in this direction, inasmuch as no 

 glandular organ within the human organism can compare 

 with it in the extent and variety of its excretory facilities. 

 Thus, we claim that special, as well as general, facilities, 

 are provided for these excretory purposes almost every- 

 where around the periphery of the entire systemic nervous 

 system, as well as by every nerve terminal within the 

 internal structures of the body, so that this fluid can 

 never everything being physiologically correct and 

 sound become a source of danger from over-pressure, 

 or fail to afford relief when pressure becomes dangerous, 

 from outside or inside, hydrostatic or hydro-dynamic, 

 circumstances. These excretionary provisions consist 

 we may again say to ensure familiarity with the subject 

 of the following amongst others, viz. the olfactory 

 mucosa, the tonsillo-glosso-pharyngeal mucosa, and the 

 coccygeal gland, excretory mechanisms, along with the 

 peripheral nerve terminal developments, and sweat 

 glands, as well as the motor nerve and plates, and 

 sarcolemmar sheaths, with their tendonous, periosteal, 

 synovial, and osseous continuations and connected sys- 

 temic lymphatics. 



The quantity of this fluid, for the time being, must 

 necessarily depend on the exigencies of the intra-systemic 

 nervine pressure, being regulated by the vaso-motor 

 agencies of the pial vasculature, so that a state of 

 hydrostatic equipoise can be maintained within, without, 

 and throughout, the entire nerve developments of the 

 body, by a continuity of circulatory facilities, and excre- 

 tory agencies, of an absolutely complete, and effective, 

 character. Inside this regulated, soft, and fluid, barricade, 

 safe from the concussion and friction of the outer world, 

 the great nerve organism is "at liberty," and can, therefore, 

 perform its varied and manifold secretory, and other 

 functions, tranquilly, and rhythmically, in accordance with 

 physiological, and psychological, law and order. 



The comparison would not be complete were we to 

 omit that great nervine secretion which takes place in
